Many on this site have changed the lowers, myself included. A few have changed upper and lower.

What are you wanting to do with yours? Drag, road race, improve launch etc?
 
I was thinking the lower I was going to get non adjustable because I never tracked it before. I need to go to a class first. I only dragged raced before not with the boss my old 04 Mach

This is a great place to ask. I have noticed two distinct groups of expertise on the site. Guys who know how to prepare a car for road racing and those who know drag racing mods.

I to have limited experience with modifying a Mustang. Reading several of the threads and asking questions I decided to go with LCAs, relocation brackets, adjustable Panhard bar and lowering springs. All from FRPP.

This mod did stop the wheel hop I was experiencing.

Do you need all these parts to stop wheel hop? Not usually. I attributed the hop to soft bushing in the factory LCAs as well as flex in the arms themselves. I still have the factory upper arm and now experience no wheel hop.

I would recommend starting with Lower arms and relocation brackets. There are several manufactures and dozens of suppliers. Many offer discounts to BMO members. Other have periodic sales ranging from 5-15%. If you have the time, shop around.

Good luck and welcome.

I have done LCA's on my BOSS. They are BBR billet pieces. it reduced wheel hop but didnt cure it on all road surfaces. I have an adjustable UCA from steeda and their UCA Bracket to install. I hope this gets rid of it. next step for me will the LCA relocation brackets. I am hesitating on getting those as it requires welding if you are going to drag race and use slicks.
 
I've done the LCA's and relo brackets on the Boss, a lot of improvment. Before the boss I had a superchaged Bullitt that I drag raced, that had upper and lower LCA's. The lowers with the brackets are what cured the wheel hop. I later went to an adjustable upper to get the pinion angle correct after lowering and 1 piece driveshaft. At the time the only adjustable lowers had rod ends and I wanted something that wouldn't increase the road noise. I did have some trouble with a clunking noise after installing the upper after some time. Each time I found the bolt was loose. I used loctite and torqued to proper specs, but it would still happen.

I would vote no chaning out the upper its not necessary IMO. Check out Vorshlag, I seem to recall they changed out the upper for the whiteline unit and then ended up changing it back to stock.
